Answer: The correct option is b) 600
Explanation:
Molecules are formed when two atoms of same or different elements combine together.
Atoms are the smallest unit of matter that combines to form a compound.
For the given chemical compound, [tex]CH_3CO_2H[/tex]
Given number of molecules = 300 molecules
In 1 mole of the given chemical compound, there are 2 atoms of carbon, 4 atoms of hydrogen and 2 atoms of oxygen
Number of atoms of oxygen = [tex]2\times \text{Number of molecules of compound}[/tex]
Number of atoms of oxygen = [tex]2\times 300=600atoms[/tex]
Hence, the correct option is b) 600
